Lavender plant named ‘Bee Cool’

ABSTRACT

A distinct cultivar of Lavender plant named ‘Bee Cool’, characterized by its upright plant habit; dense and bushy plant form; vigorous growth habit; gray green-colored leaves; and light lavender-colored flower corollas with showy white-colored terminal flower bracts.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Lavender plant, botanically known as Lavandula stoechas L., and hereinafter referred to by the name ‘Bee Cool’.

The new Lavender is a product of a planned breeding program conducted by the Inventor in Kulnura, New South Wales, Australia. The new Lavender originated from a cross made by the Inventor of two unnamed proprietary selections of Lavandula stoechas L., not patented. The new Lavender was selected by the Inventor in 1998 on the basis of its compact and freely flowering habit. Plants of the new Lavender are more compact and more freely flowering than plants of the parental selections.

Asexual reproduction of the new cultivar by terminal cuttings taken at Kulnura, New South Wales, Australia, has shown that the unique features of this new Lavender are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Bee Cool have not been observed under all possible environmental condtitions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bee Cool’. These characteristics in combination distinguish ‘Bee Cool’ as a new and distinct cultivar:

1. Upright plant habit.

2. Dense and bushy plant form.

3. Vigorous growth habit.

4. Gray green-colored leaves.

5. Light lavender-colored flower corollas with showy white-colored terminal flower bracts.

Plants of the cultivar Bee Cool can be compared to plants of the Lavandula stoechas L. cultivar Marshwood. However in side-by-side comparisons conducted by the Inventor in Kulnura, New South Wales, Australia, plants of the cultivar Bee Cool and the cultivar Marshwood differ in the following characteristics:

1. Plants of the new Lavender have weaker lateral branches than plants of the cultivar Marshwood.

2. Plants of the new Lavender have shorter leaves than plants of the cultivar Marshwood.

3. Plants of the new Lavender have gray green-colored leaves whereas plants of the cultivar Marshwood have green-colored leaves.

4. Plants of the new Lavender have smaller terminal flower bracts than plants of the cultivar Marshwood.

5. Plants of the new Lavender have white-colored terminal flower bracts whereas plants of the cultivar Marshwood have light lavender-colored terminal bracts.

6. Plants of the new Lavender have shorter peduncles than plants of the cultivar Marshwood.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Lavender.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Bee Cool’ grown in a container.

The photograph on the second sheet comprises a close-up view of typical flowering spikes of ‘Bee Cool’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Plants were grown under greenhouse conditions which closely approximate commercial production conditions during the spring in Kulnura, New South Wales, Australia. Plants used for this description were grown for about 16 to 24 weeks after planting in 15-cm containers.

Botanical classification: Lavandula stoechas L. cultivar Bee Cool.

Parentage:

Female parent.—Unnamed proprietary selection of Lavandula stoechas L., not patented.

Male parent.—Unnamed proprietary selection of Lavandula stoechas L., not patented.

Propagation:

Type cutting.—Terminal vegetative cuttings.
